Concrete mixer hydraulic piston pump A4VTG71, A4VGT90

Description  

Shut circuit
Sequence 32
Measurements seventy one, ninety
Nominal stress 5800 psi (four hundred bar)
Optimum strain 6500 psi (450 bar)
Control gadget: (HW) Proportional control hydraulic, mechanical servo, hexagon shaft with lever to the rear.

For the drum drive in cell concrete mixers A4VTG071, A4VGT090 series.
-Variable axial piston pump of swash plate design for hydrostatic drives in closed circuit
-The flow is proportional to the generate pace and displacement.
-The stream boosts as the angle of the swash plate is adjusted from zero to its greatest benefit.
-Circulation course modifications effortlessly when the swash plate is moved through the neutral situation.
-Two pressure-reduction valves are supplied on the substantial strain ports to safeguard the hydrostatic transmission (pump and motor) from overload.
-The substantial-strain aid valves also function as improve valves.
-The built-in enhance pump acts as a feed pump and handle force provide.
-The optimum enhance force is constrained by a constructed-in enhance pressure-relief valve.
-Tapered shaft choice for immediate push shaft yoke set up.
